Hello:
I am design a tool that can connect to active directory.
I make a AD_operation class, in the class I write some method, here is a
function that i write as the following:
/// <summary>
/// check if the OU,Group or User exist
/// </summary>
///
///
/// <returns></returns>
public bool ObjectExists(string objectName, string catalog)
{
DirectoryEntry de =
Connect_Domain.AdHelper.GetDirectoryEntry ();
DirectorySearcher deSearch = new DirectorySearcher();
deSearch.SearchRoot = de;
switch (catalog)
{
case "User": deSearch.Filter = "(&(objectClass=user)
(cn=" + objectName +
"))"; break;
case "Group": deSearch.Filter = "(&(objectClass=group)
(cn=" + objectName
+ "))"; break;
case "OU": deSearch.Filter =
"(&(objectClass=OrganizationalUnit) (OU=" +
objectName + "))"; break;
default: break;
}
SearchResultCollection results = deSearch.FindAll();
if (results.Count == 0)
{
return false;
}
else
{
return true;
}
}
the function is check the active directory all the object, if find it,
record it
but when the program run it, it throws a exception at line:
SearchResultCollection results = deSearch.FindAll();
the exception is Novell.Directory.Ldap.LdapException has been thrown.
i don't know why, is there anyone can help me?
